Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article delves into the effectiveness of Bayesian discrete feedback for quantum information reclaiming, comparing it with Markovian feedback strategies. It introduces the concept of quantum channels and the Kraus representation, emphasizing the importance of feedback for coherence recovery. The study compares the two feedback strategies in qubit and qutrit channels, demonstrating that Bayesian feedback offers no advantage in qubit channels but shows superior performance in higher-dimensional channels. The authors present case studies for qutrit channels, including dephasing and amplitude damping channels, to illustrate the advantages of Bayesian feedback. The article also discusses the limitations and future prospects of these feedback strategies, providing valuable insights for further research in the field of quantum information recovery.
